What happened
The pilot was cleared for a straight-in approach and began a descent from approximately 2,000 feet above ground level (AGL) while roughly five miles from the runway. During the descent, about halfway through the maneuver, the pilot retarded the throttle to idle. However, the pilot did not apply carburetor heat during this phase of flight.
As the aircraft reached 400 feet AGL, the pilot recognized that the aircraft was too low on the approach and attempted to arrest the descent by pushing the throttle forward. Upon advancing the throttle, the engine failed to respond. The pilot then applied full carburetor heat in an attempt to restart the engine, but the engine would not restart.
